Why teams connect Copper CRM and Sage 300

Close the gap between front office and back office: Copper CRM and Sage 300 share customers and status in real time, in both directions.

Copper CRM holds the customer relationship; Sage 300 runs the operations and records behind the business. The two overlap wherever the same organizations and transactions matter to both, and when that overlap is bridged by re-keying or overnight batch, each side spends the day working from stale data.

Stacksync syncs Custom Field Definitions, People, Companies, Leads in Copper CRM with Purchase Orders, Inventory Items, AR Invoices and Receipts, AR Customers in Sage 300 field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • Mirror Copper data into Postgres so internal tools can query CRM state without extra API calls.
  • Sync Copper people and opportunities into a warehouse for pipeline reporting beyond Copper's native dashboards.
  • Replicate GL, AR, and AP detail to a warehouse for consolidated multi-company reporting.
  • Keep inventory items and quantities aligned with e-commerce and warehouse systems on a schedule.

One customer master

Where both systems keep customer or organization records, corrections in either propagate to the other, ending dual maintenance.

Where Sage 300 manages people and org data: keep Copper CRM aligned

Owners, territories, and org structure informed by Sage 300 stay current in Copper CRM.

Where Sage 300 handles order-to-cash: closed-won flows through

A deal won in Copper CRM creates or updates the customer in Sage 300 with clean data, so fulfillment and invoicing start without re-entry.
